Do We Age Fast In The Absence Of Gravity Summary

When Cooper visits planet Miller, he endures years worth of time dilation by being exposed to the gravitational pull of the black hole. This scene proposes that gravity effects time, which in fact it does. According to Camillo Di Guilio, a Neuroscientist from the University of Chieti Italy, gravity effects time, specifically the biological time of a human. In the article “Do we age faster in the absence of gravity?”, Guilio explains how the absence of gravity results in physiological defects of the human body. Guilio articulates that within days of microgravity, muscle volume is reduced significantly. This is a product of a lack in muscle protein caused by the inactivity of muscles which is in turn caused by the absence in gravity(134). Gravity
In the movie, planet Miller was right in range of the gravitational pull from the black hole. As mentioned before, black holes contain a singularity which has infinite density. That would explain the strength of the corresponding gravitational force of the black hole. According to the article “Miller (planet)” by wikia.com, the gravitational force of the black hole resulted with planet Miller having 130% of Earth’s gravity (par. 1). This would reduce the biological aging of Cooper. However, the amount of 23 years is rather large. To put in comparison, Nancy Atkinson, a science journalist for NASA, acknowledges the achievement of real time travel in the article, “Cosmonaut Sergei Krikalev, the World’s Most Prolific Time Traveler.” Russian cosmonaut Sergei Krikalev orbited the Earth approximately 804 days at the speed of 7.71 km/s. In this act he actually had a time dilation of 0.02 seconds (par. 5). This basically means that he returned back to Earth 0.02 seconds younger than everyone else. 0.02 seconds may seem very short but it still the longest recorded time dilation today. The time dilation of Cooper in comparison to Krikalev can be explained by tidal
